443163951

Overview

Fair-Rite Products Corp. part number 443163951 is a solid, free-hanging ferrite core designed for electromagnetic interference suppression. It utilizes Fair-Rite Material 43 and provides an impedance of 290 Ohms at 100 MHz. The component features a rectangular geometry with an internal dimension of 2.051 inches wide by 0.051 inches high (52.10 mm x 1.30 mm) and an external dimension of 2.670 inches wide by 0.320 inches high (67.82 mm x 8.13 mm).

Feature Summary

• Solid construction suitable for multi-conductor flat cables.
• Material 43 composition optimized for high-frequency noise attenuation.
• Free-hanging design allows for easy installation on existing wiring.

Applications

• Suppression of common-mode conducted EMI on flat ribbon cables.
• Noise filtering in digital signal transmission lines.
• EMI mitigation in computer peripheral interconnects.

Procurement Notes

Verify the specific impedance rating required for your application against the datasheet value of 290 Ohms at 100 MHz. Confirm that the physical dimensions accommodate the target cable width and thickness. Ensure compliance with RoHS3 standards if applicable to your manufacturing environment.

Selection Notes

Select this component when dealing with flat cabling rather than round wires due to its specific cross-sectional profile. Material 43 is appropriate for frequencies ranging from several megahertz up to hundreds of megahertz. Ensure the cable fits within the 2.051-inch internal width constraint.

Part Context

This component belongs to the Fair-Rite Snap-It series, which are split-core or solid ferrites intended for rapid deployment on cables without desoldering. Part 443163951 specifically targets flat cable geometries, distinguishing it from cylindrical cores used for round conductors.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative Material 43 flat cable cores based on dimensional fit and impedance curves.
